MEASURING DEVICE.

Specification of Letters Patent.

Patented Apr. 1'0, 1917.

Application filed January 25, 1915. Serial No. 4,164.

To all "whom it may concern:

Be it known that I, Crmunns Winona, a subject of the King of England,and a resident of mast San Diego, in the county of San Diego and Stateof California, have invented certain new and useful improvements inMeasuring Devices, of which the following is a specification.

My invention relates to a device for tale ing measurements moreparticularly to be used by carpenters and mechanics for takingmeasurements for fitting purposes.

The objects of my invention are, first, to provide a device of thisclass which is very simple and economical of construction, second, toprovide a device of this class the clamping portion of which is readilyapplicable to different sized strips of wood for measuring purposeswhich may be picked up on the job for use, third, to provide a device ofthis class which will readily hold the two strips in their properposition and not allow them to slip and fourth, to provide a clampingdevice of this class that may be used for other purposes by a carpenteror mechanic.

With these and other objects in view as will appear hereinafter myinvention consists of certain novel features of construction,combination and arrangement of parts as will be hereinafter described indetail and particularly set forth in the appended claim, reference beinghad to the accompanying drawings and to the characters of referencethereon which form a part of this specification, in which:

Figure 1 is a perspective view of my device complete showing fragmentaryportions only of the wood strips, Fig. 2 is a sectional view of theclamping portion of my device shown closed up more than that of Fig. 1.

Similar characters of reference refer to similar parts throughout theseveral views.

The strip 1, strip 2, clamp piece 3, clamp piece 4, and cam piece 5constitute the principal parts of my device.

The strip 1 may be any ordinary strip of the usual seven-eighths inchthickness that may be picked up on the job and for some purposes whereit is desired to use a measuring piece of the same length for severaltimes it is desirable to fasten this strip 1 at a suitable place to theclamp which is done by means of the screw 3* in the clamp piece 3 or acouple of small nails may be driven through the holes 3 into the strip 1which will secure this strip 1 to the clamp piece a but it extends inthe opposite directionfrom the strip 1 so that the extended ends of thestrips 1 and 2 may be placed in the position desired for the measuringand then clamped together. The clamp consists of the two L shapedmetallic pieces 3 and 4 and the cam piece 5. The L shaped metallic piece3 is provided with two liigs 3 preferably integral with the sides of themetal and adapted to extend over the sides of the clamp piece l and theclamp piece 4 is provided with two lugs 1, also integral with the sidesof the metal extending over the sides of the clamp piece 3. These clamppieces 3 and 4 on the extended ends 3 and 4 are knurled on their innersurfaces as shown best in Fig. 2 of the drawing. These two clamp pieces3 and 4 are held in sliding position to each other by means of the rivet5 which is secured in the piece 3 but is mounted in a slot 4 in theclamp piece 4 and extends through the cam piece 5 providing a pivotalmounting for said cam piece 5 and leaving a space between the cam piece5 and the clamp piece 3 suflicient to allow the clamp piece 4 toreciprocate between these two pieces. The cam piece 5 is shaped as shownin the drawings and is provided with a semi-circular slot 5 therein.This semi-circular slot 5" is eccentric with the rivet 5 upon which thecam piece 5 is pivotally mounted, and rigidly secured to the clamp piece4: is a lug 45 adapted to extend through the semi-circular slot 5", sothat when the cam piece 0 is turned on the rivet 5 the clamp piece 4will be moved on said rivet relatively to the piece 3, thus providing aclamp for clamping the strips 1 and 2 together. The cam piece 5 isprovided with two integrally extended lugs 5 to facilitate the movementof the cam piece by the hand of the operator.

Though I have shown and described a par ticular construction,combination and arrangement of parts I do not wish to be limited to thisparticular construction, combination and arrangement, but desire toinclude in the purview of my invention the construction, combination andarrangement substantially as set forth in the appended claim.

It is obvious that with this construction there is provided a device formeasuring purposes which is very simple of construction and easy ofoperation; that the strips land 2 may be readily picked up on the job bya carpenter or mechanic and readily secured to the clamp piece ifdesired; that the clamp piece will secure the two strips together sothat measurements may be taken accurately with the device as a whole;that the strips 1 and 2 do not need to be carried with the clamp but maybe thrown away when through with them on the particular job and may besubstituted with others at any time; that the clamp may be used forclamping small pieces together for gluing purposes and for otherpurposes by the carpenter or mechanic as desired.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

In a device of the class described, the combination of an L shaped pieceprovided with a slot therein and a circular lug projecting therefromanother L shaped metallic piece slidable relatively thereto by means ofa rivet engaging said slot and means for sliding and holding these twopieces relatively to each other comprising a metallic piece providedwith a semi-circular slot therein adapted to fit over said circular lugand to slide thereon, pivotally and irremovably mounted on said riveteccentrically to said slot.

In testimony whereof, I have hereunto subscribed my name in the presenceof two 35 subscribing witnesses.

CHARLES WILDER.
